ImportError: No module named svmcmpl

ImportError: No module named svmcmpl

我正在研究 SVM,我发现了一个有趣的例子 here。我已经安装了 cvxopt,但是 svmcmpl 没有和 cvxopt 一起安装,而且我没有找到如何安装它。在页面中提到 chompack 但我也安装了它。

>>> import cvxopt
>>> import chompack
>>> import svmcmpl
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named 'svmcmpl'

如果我尝试使用名称 svmcmpl 通过 pip 安装,我得到:

$ pip install svmcmpl

我给这篇文章的作者发了邮件,他给了我答案。

svmcmpl 根本不是一个模块,它是一个脚本,可以在文章的站点 here.
